Server operating system version

CentOS 6.10

Plesk version and microupdate number

Obsidian 18.0.21

Hello,
I have a vps with Obsidian 18.0.21 version of Plesk (OS CentOS 6.10)
I would like to upgrade my current version MySQL 5.1 and PHP 7.3
but the system does not offer me a Plesk update and the current versions of MySQL and PHP are at the max of what the system offers me...
When i go to Tools=>Update i have this message (see attach file)
maybe do i have to update by command line ? but i don't know how do that...
Can you help me ? thank you

Your server OS (CentOS 6) is no longer supported because is has (long) reached it's End-Of-Life (EOL). To receive updates for Plesk you'll have to migrate to a server with a newer OS that's still supported by Plesk. You can see which OS'es are currently supported here: Software Requirements for Plesk Obsidian
